The heat exchanger shall be constructed from aluminium fins and copper pipes with a nominal outside diameter of 15 mm. The maximum chilled water pipe work operating pressure is 1.0 MPa. All joints shall be fully soldered and factory pressure tested.

Halton is specialised for customised products to meet special demands in project. Possibilities for special outlooks and multiservice products where are integrated lights sensors and other special demands.

Weights, kg/m (including water)

Halton CPA has side flanges made from steel The modular perforated screen (holes 10 mm / 50% free area) is produced in pre-painted sheet metal, RAL 9010. The coil is made from Ø15 mm copper pipes bonded to aluminum fins.

The passive beam operates by natural convection, removing the heat load from the room and replacing it with a cooling airflow. The convective airflow (output) increases or decreases in proportion with the heat load within the occupied zone, securing an optimal thermal comfort. Varying sensible cooling output requirements are met by regulating the flow of chilled water through the beam heat exchanger. This is controlled by a combination of room thermostat and water valve. Operating at elevated chilled water temperatures (to avoid latent cooling), the opportunities for free-cooling are significant.

The chilled beam Halton CPA is installed fully exposed below a ceiling or suspended ceiling. In order to ensure effective convection, the beam should be mounted at a minimum distance from the ceiling equal to 0.25 x the width of the beam, when installed away from wall surfaces, or 0.5 x beam width when installed close to partition walls.

Each chilled beam is fixed to the ceiling with expansion anchors and threaded drop rods (not included in the delivery). Four assembly brackets are fixed one fifth of the unit length (L/5) away from the end of the beam. There will be six assembly brackets with beam length ³ 3500. The exact positions of the brackets are adjusted according to the rod position.

The chilled beam position can be easily adjusted both horizontally and vertically. Assembly brackets are supplied as standard in the package. The contractor shall supply threaded rods and expansion anchors.

The Halton CPA chilled beam requires minimum maintenance. It may be necessary to clean the cooling coils every three to five years, depending on room conditions and air quality. The casing may be cleaned with a damp cloth. The cooling coil can be cleaned using a vacuum cleaner.
